Shares in Alibaba traded up as much as 7% – the company’s highest rise this year – in Hong Kong on Wednesday after SoftBank executives denied any involvement in Alibaba’s stock filling, a move which triggered analyst speculation that the investor was planning a possible sell-off of shares in the Chinese tech giant. SoftBank executives said the company wasn’t responsible for the Alibaba share registration in a private post-result briefing on Tuesday, Bloomberg reported. Shares in Alibaba dipped earlier this week after the company registered one billion American depository shares with the US Securities and Exchange Commission.
